The complete chloroplast genome of a fern genus Thelypteris interrupta

Abstract

In this study, we report the complete chloroplast (cp) genome of Thelypteris interrupta, a fern member, and comparative analysis with its related family members. The cp genome was 155,983 bp long, with a typical quadripartite structure including a pair of inverted repeat regions (25,614 bp) separated by a large (82,769 bp) and small (21,986 bp) single-copy (SC) region. The genome encodes a total of 88 protein-coding genes, 35 tRNA genes, and 8 rRNA genes. Additionally, we identified 86 RNA editing sites in 52 genes; most of the substitution was U to C (52 sites), while C to U conversion occurred in 34 positions. The phylogenetic analysis strongly supported the relationship of T. interrupta with Ampelopteris prolifera and Christella appendiculata of Thelypteridoideae family.
